About Survivair / Willson Double Bib Assembly W/o Hose
Double Bib Hood Polyester Lens Ratched Suspension Schrader Fitting The positive pressure of a Supplied Air Hood provides greater wearer protection than negative pressure and eliminates the need for fit testing. The lightweight hood provides a loose, comfortable fit and features a ratchet suspension that can be easily adjusted through the hood with a simple turn of the knob. Airflow is directed over wearer's head and across facepiece, keeping lens fog-free. The polycoated DuPont® Tyvek® double bib provides excellent splash/contamination protection and has an inner bib that tucks into protective clothing. The durable, spiral steel reinforcement in the heavy-duty breathing hose makes it nonkinking and crush-resistant. Model 4111B features an economical acetate lens that is ideal for applications where solvent attack is not a problem. Model 4211B features a solvent-resistant polyester lens. Both models have a Schrader 1/4" twist-lock (B) fitting. NIOSH approved. Sperian 14510025 Survivair / Willson Double Bib Assembly w/o Hose (4211B) WS14510025
